CI e2e test can fail with iperf3 test

[louiznk]

Expected Behavior

When runing e2e test results should be immutable.

Current Behavior

Sometimes and without changing the original code it's fail. Not only times, it's not predictable.

The error on e2e test is

iperf3: error - unable to send control message: Bad file descriptor

Possible Solution

The cause is that the docker container which is going to "accept" iperf3 request is ready after the request is done.

See the PR : #1599

Steps to Reproduce (for bugs)

Relaunch several time e2e

Exemple of build fail from master : https://github.com/louiznk/flannel/runs/7020788240?check_suite_focus=true#step:5:226

Context

If the E2E fail for some wrong raison it's not helping on the code

Your Environment

It's on github action on master branch and I suppose other branch

It's arrive less frequently on my laptop (linux)
